Personally speaking, I would still choose to get married, only because it says alot about the relationship & the committment amongst the two of you. You were a team before the children, so why not choose to continue along those lines in a Godly manner. When I say Godly, I mean when you make the vows, nothing should change in your realtionship other than your choice to have a single partner for life and you are now joining in a union of being one and not seperate. The thing people forget these days is they are always looking for too many expectations, other than just letting life take its course and enjoying it. It is better to have loved than to not have loved or known love at all.... As well I agree with caramelsugarberry38.

I would like to suggest that you & your hubby choose one night a week, that is best for both of you, then maybe see if a babysitter or maybe the Grandparents or relatives would not mind babysitting for a night.
When I lived in New York, my family would help me out. That was great. It is a little harder now for me now as well, so I understand.
